MHI sees a future for both steam and all-air cooling: Recently launched gas turbine concepts from MHI include the J-series, a further evolution of its well established steam cooled technology and the M501GAC return to all-air cooling

摘要

With over sixty of its G machines (G, G1 and G2) sold since 1997, MHI has a larger fleet of operating steam-cooled gas turbines than any other vendor, and is planning to take the technology to new levels of efficiency with its recently announced J-class gas turbine (see Figure 1 and Modern Power Systems, April 2009, p4). But the company has also recently taken a step in a very different direction, with the launch of a fully air cooled version of the G, the M501GAC - with the aim of responding to user demands for flexibility.
